GALVANIC CELL.

No Drawing.

To all whom 1' t may concern:

Be it known that I, MORDUCH L. KAPLAN, a citizen of the United States,and a resident of Brooklyn, in the county of Kings and State of NewYork, have invented certain new and useful Improvements in GalvanicCells, of which the following is a specification.

The object ofthe present invention is to provide a good depolarizer forthe galvanic cell of the Leclanch type.

I have discovered that potassium manganite when treated with a dilutesolution of a manganous salt, is changed into a .dark colored manganouspolyinanganite according to the following equation:

I have further discovered that this hy- Specification of Letters latent.Application filed June I,

blue hydrated Patented Sept. 1, 1914.

1914. Serial No. 842,021.

' drated manganous polymanganite when heated in the air, can be made tolose nearly all its water without any appreciable loss of oxygen. Bothproducts, the hydrated as well as the dehydrated, are deep, bluishdarkcolored, fine dense powders, excellent depolarizers, and give goodresults when used in-the Leclanch cell, in relation to yield andsteadiness of current.

What I claim as my invention and desire to secure by Letters Patent, is:

A galvanic cell containing manganouspolymanganite as a depolarizingagent.
